Take advantage of office hours. When you must miss a class, e-mail the professor. Proofread your work. Thank the professor for a particularly interesting class. Take […]
How do you find velocity before hitting the ground?
How do you explain pressure altitude?
How do you explain pressure altitude? Pressure altitude is the attitude displayed on the altimeter when the Kollsman window is set to 29.92 inches of mercury, or 1013.4 millibars. Pilots cannot use pressure altitude below 18,000 feet, because then the aircraft’s true altitude would change depending on temperature. Why do we calculate pressure altitude? Pressure […]
What are ferromagnetic and antiferromagnetic materials?
What are ferromagnetic and antiferromagnetic materials? Ferromagnetic materials have magnetic moments that align parallel to the applied magnetic field whereas antiferromagnetic materials have antiparallel magnetic moments. Therefore the magnetic moments still cancel each other out and the overall magnetization is zero. What is hysteresis loop explain with diagram? A hysteresis loop shows the relationship between […]
Why is it called a diverging lens?
How do I get rid of the small screen on my TV?
What is called critical angle?
What is called critical angle? When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees. This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. Why […]
Why does massless light bend near a large mass?
Why does massless light bend near a large mass? Light can form a curve if it travels near a big mass. You are right, photons don’t have mass. You are also right, photons doesn’t follow Newton’s gravitation law. Photons can be pulled by gravity not because of their mass (they have none) but because gravity […]
What is periodic table and its properties?
What is periodic table and its properties? The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. What are two characteristics of elements? All elements have […]
What is SI unit of merit?
What is SI unit of merit? Figure of merit is the amount of current been passed in the unit of deflection in a galvanometer. Its SI unit is Ampere per division. What’s the difference between a galvanometer and a multimeter? The galvanometer is converted into the ammeter by connecting the resistance in parallel with the […]
